Frontier coding and agent performance at roughly half the Opus price, and the sensible default for everyday work. 1M context, adaptive thinking, strong tool use.

To keep the service available, Claude Sonnet 5 and GPT-5.6 Luna each have their own concurrency limit. Sonnet 5 allows up to 10 in-flight requests and may queue briefly during busy periods; Luna allows up to 15 and returns 429 immediately once they are all in use, so retry after a moment.

Claude can only be billed from the paid Wallet. Credit and Reward balances cannot pay for Claude requests.
